Hochiki - Explosion Proof Systems

The explosion-proof fire alarm system consists of equipment that is installed in areas where there is a risk of explosion. The equipment must not cause an explosion, and this is achieved by limiting electrical and thermal energy by releasing low voltages that enter the high-risk area.

Products are certified by BASEEFA, IECEx and ATEX.

The system is adaptable to a wide range of applications and can be adapted to almost any environment, from small to very large areas. Examples of such environments are oil, gas and chemical plants, biomass production, waste processing plants, gas stations and boiler plants.
